I have been using the kernel-lt series in Scientific Linux (now 7.8) for 
years, because the standard kernel has not respected the 'adapter_nr' 
defined in /etc/modprobe.d/dvb.conf

After today's update my twin-dvb usb TV device could not be initialised. 
  Reverting to 4.4.226 works, but only after I had unplugged/replugged 
the usb device.

This is a heads-up.  My system is working again and I have not yet 
reported to the sites quoted above.
